To @ZZ whom t 77mg/ concern:

Be it known that we, HENRY HARRISONV YORTY andJonN S. PURDY, citizens of theV United States, residing Yat Houston, in the county of Harris and State of Texas, have invented a new and useful Incandescent Hy-n drocarbon-Lamp, of which the following is a specification.

This invention relates to hydrocarbon burners, and particularly to an incandescent Y furthermore, to provide gas-generating meansA in connection with `one burner for supplying an additional burner or burners within a cluster or number of lamps supported by the same pendant.

Furtherobjects and advantages will be hereinafter disclosed in the description and the novelty expressed inl the claims, and an embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a sectional elevation of an apparatus embodying the invention and showing two burners. Fig. 2 is a detail sectional view of the initial vaporizing device. Fig. 3 is a top plan view of a part of the generator and valved feeding attachment therefor. Fig. 4 is a detail sectional view of one of the valves.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a reservoir, which may be of the form shown or of any other ornamental character, and has connected to the upper part thereof asuspending-devi'ce', such as ahook 2. Depending fromthe lower portion of the reservoir is a pipe or tube 3, which serves as a conveyor for the oil from the reservoir and also as a means of supporting the devices below, and by means of an intermediate collar 4 a lower gas pipe or tube 5 is held on the pipe or tube 3 and connectedat its lower terminal, through the medium of a T-coupling 6, with laterally-extending horizontal branch pipes or tubes '7. The outer terminals of the pipes or tubes have elbows 8 connected thereto, and on their upturned ends burners 9 are secured and supplied with chimneys 10 and mantles 11 of any preferred form, but preferably of the Welsbach character. Two burners 9 areshown in the drawings, together with the necessary equipments therefor; but it will be understood that it is the intention of the invention to use any number of burners within a cluster or group and have the gas-generating apparatus for all disposed over and controlled by one of the burn ers only. The gas-feeding pipe or tube 5 has its upper end 12 closed, so as to forni a partition between it and the oil-feeding pipe or tube 3 for obvious reasons.

Communicating with the collar 4 is the upper end of a generator 13, consisting of a pipe or tube of suitable dimensions and extended outwardly and downwardly by regular bends to a lower horizontal leg or member 14, which stands closely over the upper terminal of the chimney 10 of one of the burners, as shown, and from' thence is extended to forni a valveseat extremity 15, in which is adjustably mounted a valve 16 of the form of a screwV and having a turn head or wheel 17 attached thereto for adjusting purposes. A collar 18 is fitted over an opening 19 in the upper part of the pipe or tube 5, below the upper closed end 12, and communicating with said collar "18` is the upper end of a combined mixing and starting tube 20, having its opposite end extended downwardly and reduced, as 'at 2l. Within the tube 20, at a predetermined distance from its opposite terminals, is an inclined deiiector 22, from which the mixing-tube may be curved downwardly in such manner that the gasolene or fluid used in the lamp will be effectively conducted to the reduced end of the said tube. Connectedto said tube below the defiector and at a suitable angle is a nipple 23, having a sleeve 24 adjustably mounted thereon. Be-

ICO

disposed relatively to the valve-seat extremity of the generator, so that the injection will take place in a direction centrally of the Said nipple in a longitudinal line.

. As will be understood the injecting-orifice 27 is very small and its dimension is controlled by a Valve 28, adjustably mounted in the injector and also of the screw type. The said ejector also has attached thereto a drippan 29, into which a small quantity of the oil may be run by partially opening the valve 16 for the purpose of heating the generator 14 and valve 16 to generate gas in case it is not desirable to use mixing-tube 2O and receiver, hereinafter setforth, for that purpose. This obviates the application of alcohol for similarpurpose in ordinary devices and which is required to be held u p bya containing device adjacent the parts, which will be effected in the present instance by the ignited oil in the pan 29.

Over the burner 9 and within or at the top of the chimney 10 is a receiver 30, of any suitable material indestructible by fire, preferably sheet metal. This receiver comprises a surrounding wall 3l to protect the chimney and has hooks or analogous devices 32 on its upper portion. The lower inner portion of the receiver is in the -form of a gutter, angular trough, or cup of any shape and adapted to hold a small quantity of the ignitible lluid, asbestos,or other uniniammable material that will absorb the uid and which may be separate and apart from the receiver 30 and attached to the mixing-tube 20, generator 13, or any other part of the lamp burner or receiver 30 that Will support it under said generator and above burner and of any suitable material. The lower reduced end 21 of the mixing pipe or tube 2O is extended into the said trough and the wall 31 shields and protects the upper part of the chimney 10.

In the operation of the device the oil from the reservoir 1 flows down through the pipe or tube 3 into the generator 13, and the Valves 16 and 2S are regulated to permit a small quantity of the oil to be injected into the nipple 23 and by the deector 22 in the mixing-tube 2O is directed down the tapered outer extremity of said tube to the reduced end 21 and from the latter into the trough 33 at the lower end of the receptacle 30 within the chimney 10. The oil that is deposited in the said trough 33 is ignited and allowed to burn under generator-leg 14 and valve-seat 15 to rapidly heat and vaporize the oil which flows down through generator 13 and cause the gas to be thrownby the injector into the tube 20 and to the left, as the parts are positioned, to

the gas-feedin g pipe or tube 5, and then to the burners 9. The gas from the injector will be drawn or sucked by the blaze within the gutter or trough 33 and will also be prevented from passing down through the tapered eX- tremity of the mixing-tube 20 by the quantity of oil that Will still remain in the latter, and the oil Within the trough 33, being ignited at this time, will also cause an ignition of the gas that has reached the burner 9. It will be seen, therefore, that almost simultaneously with the initial heating for starting vaporizalion the one burner will be ignited and successfully carry on the formation of gas in the generator without loss of time or requiring an extended continuation of initial heating or starting means for inducing vaporization. The remaining burners must be lighted in the ordinary manner, and the combustion taking place at the burner'will set up a suction which draws the gas as formed rapidly through the pipe or tube 5.

As will be understood, the feeding end of the injector 25 will be at a distance from the terminal of the nipple 23 in order to draw in air and set up the necessary mixture of gas and air within the tube 2O and which is regnlable in accordance with surrounding drafts or currents by the sleeve 24, adjustable on the said nipple. It might also be supposed that the gas injected into the tube 20 would escape through the tapered extremity of said tube instead of flowing into the pipe or tube 5; but the suction of combustion in the several burners will be so great as to overcome this tendency completely, and, furthermore, what little gas may flow into the said tapered extremity will immediatelybecome superheated and exceptionally light and will take the direction of escape which offers the least obstruction and which will be through the upper terminal of the said tube 2O into the pipe or tube 5.

The quantity of gas flowing through the injector 25 Will be regulated by the valve 28, and the amount of gas passing from the valve-seat extremity 15 of the generator to the injector 25 will be controlled by the valve 1G, and it will be observed that there is no valve controlling the flow of oil. The oil is l permitted to have unobstructed feed into the generator 13, and the gas being formed only at one point or by means of but one apparatus must feed rapidly and in large quantities to supply the several burners with a sufficient amount for practical illuminating purposes. Consequently the iloW of oil into the generator must be constant and the feed of the latter in said generator to take the place of that vaporized must be rapid. Vlhile the process of vaporization will take place mainly in the leg or member 14 of the generator, in view of the proximity of such part to the burner of the lamp the Whole generator will become heated to a greater or less extent and prepare the oil for rapid vaporization before it reaches the said'leg or member 14. In the initial heating of the lamp the oil for starting purposes will be injected into the tube 20 with considerable force, in View of the elevation of the source of supply above the injector 25, and after ignition of the oil in the trough 33 of the receptacle 30 the oil that may remain in the generator between the leg or member 14 and the valve-seat extremity 15 'will become rapidly vaporized and will almost immediately pass out in the form of gas.

In using the improved apparatus in connection with clusters or groups of lamps of large capacity or of normal capacity and large numbers it may be necessary to materially increase the dimensions of all the parts and also change the location. This variation will be made, and also changes in the proport-ions and form as Well as minor details of construction will be resorted to Within the scope of the invention and Without sacrificing' any of the advantages thereof.

Having thus described the invention, what is claimed is-` g 1. In a lamp of the character set forth, the combination with a number of independent burners, of a gas-forming apparatus for the burners arranged completely above all the latter and wherein the gas is generated ex; clusively by one of the burners which is also used for illuminating purposes, a portion of the said gas-forming apparatus extending adjacent to the generating-burner and adapted to contribute to the automatic ignition of the latter.
